PACKING-MACHINE Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed January 4, 1907. Serial No. 350,792.

the object of the invention is to provide an improved machine of this class whereby the operation thereof is facilitated and rendered more simple and effective, and whereby the danger of breaking a machine is obviated, and whereby the power shaft of the machine may be automatically and easily thrown out of gear' whenever desired.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which;-

Figure l is a front view of a machine of the class described provided with my improvement; Fig. 2 a view of the right hand side thereof g Fig, 3 a partial view of the left hand side of said machine; Fig. 4 a back view of parts of the machine including the table or carrier which supports a barrel or other receptacle to be filled; Fig. 5 a section on the line 5 5 of Fig. 4; Fig. 6 a sectional side view showing details of the tripping mechanism by means of which the power shaft is thrown out of gear; and, Fig. 7 a plan View of a part of the construction shown in Fig. 6.

My invention is applied to a machine of well known construction having a main frame comprising two pairs of vertically arranged side standards a connected at the top and bottom in any suitable way, or by base members a2 and top membersr a3. Mounted transversely of the main frame and between the separate pairs of side standards is a shaft b having one or more drums b2 on which are Wound chains or similar devices b3, and mounted in the main frame below the shaft b and between the side standards a is a rectangular barrel supporting frame d composed of transverse top and bottom members d2 and vertically arranged side members (Z3, and this frame is provided with a suspending device comprising a rod d4 provided at its upper end with a transverse link d5 with which the chains d3 are is connected a chain b5 which passes over a pulley b'I with which is connected a chain bs which, in practice,

is suspended from any suitable overhead support, and placed back of the machine in any suitable position are Aa plurality of weights f loosely connected by links f2 and pins f3 secured to said weights and the chain b5 is connected with the top weight f and all of said weights are mounted on two vertically arranged rods f4 secured to a base f5 on which the weightsf rest. At the top of the machine is a hopper g having a downwardly and forwardly directed part or member g2 having a base member g3 below which is placed a cylindrical continuation g4 of said chute which is secured to the base portion g3 and which is adapted to fit, or fit in, the top of the barrel e placed on the table or support d. At the top of the main frame and secured to the front portion thereof is a yoke-shaped bracket h provided with a vertically arranged shaft h2 having a beveled gear wheel h3, and in said bracket is mounted a horizontal shaft h4 provided with a beveled pinion h5 which meshes with the gear wheel h3, and the shaft h4 is provided with a drive pulley h6 and idler pulley h7. All these features of construction as hereinbefore described are old and well known, and form no part of this invention and in machines of this class the lower end of the shaft h extends downwardly and is provided with a packing screw or spiral hs which is indicated in dotted lines in Fig. l, and which in the operation of the machine is revolved and serves to pack the material in the barrel e.

Below the outer end of the shaft h4 is a horizontal arm t' which is secured to the main frame and which is provided with two pins i2, and mounted on the pins t2 is a slide plate t3 having two slots i4 through which said pins pass, and the slide plate i3 is provided with a shifting fork t5.

At the inner end of the arm i is a pulley i6, and at the outer end thereof another pulley i7, and a cord 8 is connected with the outer end of the slide plate i3 and passed over the pulley i7 and carried back and passed over a pulley y' supported at the side of the machine, and connected with said cord are weights j?, and said weights may be separated so as to regulate the amount of pull on the cord is.

Connected with the inner end of the slide plate i3 is a cord 3'3 which is carried backwardly and connected with a lever jM1 pivoted to the side of the main frame at j5, the connection of said cord and the lever jf being shown in dotted lines in Fig. 2 and indicated in full lines in Fig. l, and said lever projects forwardly as clearly shown in Fig. 2. In front of the right hand side of the main frame and adjacent to the lever j4 is mounted a vertically movable rod k the upper end of which passes through a keeper k2 secured to the main frame, and connected with said rod k below the lever j4 is a fixed sleeve k3 with which is connected a link k4 which is connected with the lever j* at c5.

Below the sleeve k3', the rod 7c is provided with a.

cam sleeve kf' the inner side of which is provided at the bottom thereof with an inclined cam surface k7, and secured to the upright frame member a is a plate m having a transverse and horizontal bottom member m2 provided at its right hand end and at the right hand side of the machinewith a head m3 having an inclined surface which corresponds with the inclined surface k7 on the cam sleeve lcG and forming a projecting nose m4.

Below the part m2 oi the plate m is a horizontally and transversely movable-plate n having a slot 'n2 through which passes a headed pin n3 secured tol the plate m or the part m2 thereof, and the plate n is provided with -two pins n4 and a5 shown in full lines in Fig. G and dotted lines in Fig. 47, and the right hand end of the plate n is provided with an opening a6 through which the rod lc and the cam sleeve 7cG are adapted to pass. I

Secured to the side of the main frame member a., below the plate m, is a spring arm o, the free end of which extends outwardly and forwardly and is kcoiled around the rod c as shown at o2, and the function of the spring arm o is to pull the rod 7c inwardly transversely of the front of the machine.

Pivoted to the bottom of the part m2 of the plate m is a bell crank p the lever arm p2 of which extended outwardly and forwardly of the pins'n4 and a5 of the plate n, and the shorter arm ofwhich extends inwardly toward the center of the machine and is pro vided with a cam nose p3. Fixed to the table, o r table frame which supports the barrel e is a'verticalrod r provided near its upper` end with a sleeve r2 which supports a roller r3 which is adapted to operate in connection with the cam nose p3'- of the bell crank p.

The vertically arranged side members d3 of the barrel supporting frame d is provided at the top thereof with transverse guide plates s which overlap the upright members a as shown in Fig. 5, and one of said plates is provided with a support s2 in which the upper end of the rod r is secured.

The central part of the shaft b which is clearly shown in Fig. 4, is back of the chute member g'i and the drums b2 and chains b3 do not show in Fig. l, but said shaft and the drums thereon are clearly shown in Figs. 2 and 4. n

The shaft b is provided at its left hand end as shown in Fig. 3,'with a brake device comprising a friction drum t to which is fixed a hand Wheel t2 and the friction drum t is provided with a friction band t3 one end of which is secured to the framework at t4 and the other end of which is connected at t5 with the shorter arm of a lever t6 pivoted at t7 and provided with a weight t8. The lever t6 may be thrown out of operation by means of an arm u l'pivoted at u2 and provided with a nose a3 adapted to bear on the lever t6, and by means of an adjusting screw a4 supported by the main frame the frictional tension of the band t3 may also be regulated. rlhis brake device forms no part of my invention and any suitable device of this class may be employed.

The operation of my improvement is as follows. In practice the table dG is lowered and the barrel e is placed thereon, and in the operation of lowering the table dG the weights f are raised and the friction device at the left hand side of the machine regulates the upward movement of the table and barrel. Ther barrel, being.

in position, the material is dumped o1' poured into the hopper, and thisv'operation is also regulated so as to control thendischarge of the material into the barrel. At'this time or when the material begins to descend into the barrel the lever jiis inn its raised position and the belt uV is on the idler k7. The lever 74 is now depressed and this operation throws the belt v onto the driving pulley h6 and the shaft h is rotated and the material is gradually and firmly packed in the bottom of the barrel by the rotating packing screw or spiral hs. As this operation proceeds the platform and the barrel are gradually depressed by the packer, andas the platform and barrel go down the chains b3 are unwound 'and the chain b5 is wound up and this latter operation successively raises the weightsf, all this operation except the weightsf and the operation thereof being common to the old machine as now constructed. When the table is fully depressed, or to a predetermined point, and the barrel is full, the roller rr3 strikes the nose p3 of the bell crank and the longer arm of said crank forces the plate n outwardly against the operation of the spring arm o, and this operation forces the nose of the cam k7 out from beneath the nose m4 of the head m3 of the plate m or the part m2 thereof, and at this time the weights j2 operating through the cord is to raise the lever 3'4 and rod lc and at the same time the cord t8 pulls the shifting fork 'i5 to the right and shifts the belt e to the idler k7. The power shaft is now out of gear and the operation of the machine is stopped. The barrel e may now be removed from the table d and another barrel placed thereon, and it will be understood that during this operation the table ds must be held down either by' placing the foot thereon or by any other means.

By employing the weights f which are loosely connected by the link members f 2 and which are mounted on the vertically arranged rods f 4 by which they are held in proper position, the packing of the material in the barrel or other package or receptacle is regulated and made even throughout, said weights being successively raised as the barrel or other package is depressed, and in this way from twenty to thirty percent more material may be packed in the barrel or other package than by means of the old machine as heretofore constructed.

By means of this construction it will be seen that I provide a shifting mechanism which is automatically operated when the barrel or barrel supporting frame is fully depressed for throwing the power shaft out of gear .and stopping the operation lof the machine, and bymeans of this construction accidents are avoided and the operation of the machine rendered more safe andr effectual.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, isz- 1. A machine of the class described, comprising a main frame, a vertically movable barrel supportmounted therein, a hopper adapted to discharge material into a barrel mounted on said support, a vertically arranged packing shaft the lower end of which passes into said barrel when in its highest position, a pluralityof weights supported so as to be successively raised by the barrel support as the latter is depressed, a horizontal power shaft geared in connectionwith the packing shaft and provided with a fixed and a loose pulley, a belt shifter support mounted beneath the ypower shaft, a belt shifter connected with said support, a lever pivoted to the main frame, a cord connecting the inner end of the belt shifter with said lever, another cord connected with the outer end of the belt shifter and passed over a pulley supported by the main frame and provided with weights a vertically arranged rod connected with the barrel support, a vertically arrangedrod connected with the main frame, and devices connected with said rods and with the main frame and operated by the barrel support when in its lowest position to shift the belt from the fixed to the loose pulley, said belt being shifted from the loose to the fixed pulley by depressing said lever.

2. In a machine of the class described, a main frame, a shaft mounted horizontally therein and provided at one end with a drum7 a vertically movable barrel support mounted in said frame and connected with said shaft by suspending; devices wound thereon, a hopper adapted to discharge material into a barrel or other receptacle mounted on said support, a vertically arranged packingY shaft the lower end of which passes into said barrel o1' other receptacle when in its highest position, a plurality of a loose pulley, a belt shifter support mounted beneath the power shaft, a belt shifter' connected with'said'support, a lever pivoted to the main frame, `devices connected with the belt shifter and said lever for moving, the belt from4 the loose to the fixed pulley and other devices connected with the belt shifter and with the main frame and operated by the barrel support when in its lowest position to shift the belt from the fixed to the loose pulley.
